# damnesiac
easybcd dont want to start on a XP machine. so i cant use it

# crawle
so easy? so where does this chain0 lying on my leo system?!
i have to copy it on C: and i add "C:/chain0=Leopard" to the boot.ini ?

so easy?

Author Update #2 @xan 2008-02-08

tried but i get a chain error

is this because i use GUID & EFI on my leo sys? can chain0 boot guid & efi?

Author Update #3 @xan 2008-02-10

@ damnesiac: this site cant help me. i have guid and efi ! not mbr. so chain0 cant find the right partition to boot. or xp loader dont find it.
@ rfuilrez: i know your way, but my board cant boot via f8, i have to press del - 5 clicks for setting up the primary hdd - f10 - reboot - an then i have Mac... this is not the best way

i wait till rev2 and set up a new leo with mbr and then i will try chain0 again

Field Note #1 @DoiX 2008-02-04

as far as i know you cant add another volume to the bootloader, and please search before starting discussion <a href=osx.kb ot.de/comments.php?DiscussionID=112&page=1#Item_5" >here</a href>

Field Note #2 @damnesiac 2008-02-07

Try EasyBCD. It should work on XP and you can install the VIsta bootloader and then add the Leo partition into the bootlader easily.

Field Note #3 @crawle 2008-02-07

Or you copy the chain0 file from your Leopard System to the root of your Windows partition. Now add C:/chain0=Leopard to your Win-Bootloader. (only on XP)

P.s.: Select in BIOS the HDD priority to the Windows' one ...

Field Note #4 @rockyrocket 2008-02-08

Hi i use four drives in my system, one ubuntu one leo (zeph v1) vista and a storage drive.
I unplug other drives except the one installing and allow grub , darwin or whatever to think its the only os.
Then do the same with the others.
At boot i can then hit f8 on my m2n4 mobo to choose the os.
This trick works in a lot of other board-bios combos to!.

Field Note #5 @crawle 2008-02-08

@xan: I don't know if it works with GUID/EFI. Doesn't seem so. I'm sorry. With MBR that would be all...

Field Note #6 @DoiX 2008-02-08

i read somewhere in the forums that osx uses now boot0 not chain0

Field Note #7 @crawle 2008-02-09

What about Boot Camp? I'm serious! On EFI with GUID should it work, shouldn't it?

Field Note #9 @rfuilrez 2008-02-10

When my PC boots up it says "Press DEL for setup menu. Press F8 for Boot Menu" I just hit F8, and pick my Leopard drive. It works out well for me. My Win XP x64 drive is set as default for boot (for the old lady), and when I want to use it, Leopard is just an F8 away.

Setup

SATA hdd0 = Leopard GUID Drive w/ EFIv8
SATA hdd1 = Windows XP drive

Both have they're own bootloaders.
